You can no longer worry because you are not able to constantly press Lybu and regularly ask you: "What is so gloomy? What are you unhappy now?! "
Scientists from the Dutch Research Company Noldus Information Technology proved that part of people (including women) simply live with a "contemptuous" expression of the face (Resting Bitch Face), not thinking anything wrong.
It is not in constant irritation or harm. Scientists Ayb Macbeth and Jason Rogers checked the emotions of people in those moments when they have offended / dissatisfied / contempt persons. In the overwhelming majority of cases, these people have not experienced any negative emotions. That is, the gloomy physiognomy was, in their case, neutral.
By the way, the term Resting Bitch Face itself (literally something like "relaxed bodies") was divided by the Internet due to this comic video.
The makeup artists note that the view about how a calm, neutral face should look like, is now impressed by the good "treated" make-up and photoshop of persons in the mass media. In fact, without photoshop, some of the very natural features of the live person can impress sadness or discontent. We are talking, for example, about the corners of the eyes and lips, some embodiments of the nose and mouth, sometimes about ptosis.
